Diseño e implementación en un sistema de medición de temperatura de frenos de disco a bordo en un vehículo

Abstract

It is describing an overview of the most important parts of the disc braking system and its operation, safety and prevention mode. The braking elements in this case are the brake pads. The behavior of the brake pads is studied when they are replaced by alternate elements in front of the original; when by using varied materials result in different behaviors against temperature, braking distance and life time. We study the fundamental problem, which is analyzing the braking temperature, the overheating and the deterioration of the braking system. The theory describes the variables: braking distance as a function of temperature, vehicle weight and the thickness of the pads; these are details that serve to design and build a prototype capable of measuring the temperature and warning the driver. This prototype is easy to use and can be used in a variety of vehicles by modifying the entry data. By using emergency colors, a digital detail of the temperature and an alert sound indicates the overheating of the brake pad. In addition, the experimental model adjusted to the research is defined. The test vehicle is determined and the prototype warning system is placed. The proper functioning of our prototype will be controlled by other devices, and preliminary tests are determined. The analysis of the results of the dynamic tests indicates the values of temperature and braking distance, to determine the critical temperature and the loss of efficiency of the braking system. These temperatures are useful for programming the equipment.
